Well, every rifle is a little different. A little difference on the action can correspond to a significant difference of POI at 100 yds...

Having said that, though, I had problems with a set of scope rings on a Ruger No.1 RSI in 7x57, so I just took the rings and scope off my No.1 S 338 Win Mag and tightened it down on the RSI. Horizontally it was perfect at 100 yards for the 7x57, but there was quite a bit of elevation difference in the two loads.

Don't force the scope and rings from one Ruger onto another, but it may fit just fine.
